Dynamic capacity resource allocation system in computer networks

System and methods are provided that can address dynamically determining capacity allocations for multiple services on the same computing devices in the same point of presences (PoPs). A routing and capacity management system receives logs from the services. The routing and capacity management system processes logs from the services to generate data that reflects resource usage at respective PoPs and/or border links. The routing and capacity management system dynamically determines capacity allocation for the services based on the generated data and instructs the services with the capacity allocation changes.
